Moreover, it also provides some common clock code, which would +allow easy porting of CCF Linux code to other platforms. + +Design decisions: +================= + +* U-Boot's driver model [DM] for clk differs from Linux CCF. The most + notably difference is the lack of support for hierarchical clocks and + "clock as a manager driver" (single clock DTS node acts as a starting + point for all other clocks). + +* The clk_get_rate() caches the previously read data if CLK_GET_RATE_NOCACHE + is not set (no need for recursive access). + +* On purpose the "manager" clk driver (clk-imx6q.c) is not using large + table to store pointers to clocks - e.g. clk[IMX6QDL_CLK_USDHC2_SEL] = .... + Instead we use udevice's linked list for the same class (UCLASS_CLK). + + Rationale: + ---------- + When porting the code as is from Linux, one would need ~1KiB of RAM to + store it. This is way too much if we do plan to use this driver in SPL. + +* The "central" structure of this patch series is struct udevice and its + uclass_priv field contains the struct clk pointer (to the originally created + one). + +* Up till now U-Boot's driver model (DM) CLK operates on udevice (main + access to clock is by udevice ops) + In the CCF the access to struct clk (embodying pointer to *dev) is + possible via dev_get_clk_ptr() (it is a wrapper on dev_get_uclass_priv()). + +* To keep things simple the struct udevice's uclass_priv pointer is used to + store back pointer to corresponding struct clk. However, it is possible to + modify clk-uclass.c file and add there struct uc_clk_priv, which would have + clock related members (like pointer to clk). As of this writing there is no + such need, so to avoid extra allocations (as it can be auto allocated by + setting .per_device_auto_alloc_size = sizeof(struct uc_clk_priv)) the + uclass_priv stores the pointer to struct clk. + +* It is advised to add common clock code (like already added rate and flags) to + the struct clk, which is a top level description of the clock. + +* U-Boot's driver model already provides the facility to automatically allocate + (via private_alloc_size) device private data (accessible via dev->priv). + It may look appealing to use this feature to allocate private structures for + CCF clk devices e.g. divider (struct clk_divider *divider) for IMX6Q clock. + + The above feature had not been used for following reasons: + - The original CCF Linux kernel driver is the "manager" for clocks - it + decides when clock is instantiated (and when memory for it is allocated). + + - Using it would change the original structure of the CCF code. + + - To bind (via clk_register()) the clock device with U-Boot driver model we + first need udevice for it (the "chicken and egg problem"). + +* I've added the clk_get_parent(), which reads parent's dev->uclass_priv to + provide parent's struct clk pointer. This seems the easiest way to get + child/parent relationship for struct clk in U-Boot's udevice based clocks. + +* Linux's CCF 'struct clk_core' corresponds to U-Boot's udevice in 'struct clk'. + Clock IP block agnostic flags from 'struct clk_core' (e.g. NOCACHE) have been + moved from this struct one level up to 'struct clk'. + +* For tests the new ./test/dm/clk_ccf.c and ./drivers/clk/clk_sandbox_ccf.c + files have been introduced. The latter setups the CCF clock structure for + sandbox by reusing, if possible, generic clock primitives - like divier + and mux. The former file provides code to tests this setup. + + For sandbox new CONFIG_SANDBOX_CLK_CCF Kconfig define has been introduced. + All new primitives added for new architectures must have corresponding test + in the two aforementioned files. + + +Testing (sandbox): +================== + +make mrproper; make sandbox_defconfig; make -j4 +./u-boot -i -d arch/sandbox/dts/test.dtb +=> ut dm clk + +or in a more "scriptable" way (with -v to print debug output): +./u-boot --fdt arch/sandbox/dts/test.dtb --command "ut dm clk_ccf" -v + +To do: +------ + +* Use of OF_PLATDATA in the SPL setup for CCF - as it is now - the SPL grows + considerably and using CCF in boards with tiny resources (OCRAM) is + problematic. + +* On demand port other parts of CCF to U-Boot - as now only features _really_ + needed by DM/DTS converted drivers are used.

It becomes difficult to use uboot 'nand' command to write BCB since it requires platform specific attributes need to be taken care of. It is even difficult to use existing msx-nand.c driver by incorporating BCB attributes like mxs_dma_desc does because it requires change in mtd and nand command. So, cmd_nandbcb implemented in arch/arm/mach-imx BCB contains two data structures, Firmware Configuration Block(FCB) and Discovered Bad Block Table(DBBT). FCB has nand timings, DBBT search area, page address of firmware. On summary, nandbcb update will - erase the entire partition - create BCB by creating 2 FCB/DBBT block followed by 1 FW block based on partition size and erasesize. - fill FCB/DBBT structures - write FW/SPL on FW1 - write FCB/DBBT in first 2 blocks for nand boot, up on reset bootrom look for FCB structure in first block's if FCB found the nand timings are loaded for further reads. once FCB read done, DTTB will load and finally firmware will be loaded which is boot image. Refer section "NAND Boot" from doc/imx/common/imx6.txt for more usage information.

charset=UTF-8 Content-Transfer-Encoding: 8bit BD71837 and BD71847 is PMIC intended for powering single-core, dual-core, and quad-core SoC’s such as NXP-i.MX 8M. BD71847 is used for example on NXP imx8mm EVK. Add regulator driver for ROHM BD71837 and BD71847 PMICs. BD71837 contains 8 bucks and 7 LDOS. BD71847 is reduced version containing 6 bucks and 6 LDOs. Voltages for DVS bucks (1-4 on BD71837, 1 and 2 on BD71847) can be adjusted when regulators are enabled. For other bucks and LDOs we may have over- or undershooting if voltage is adjusted when regulator is enabled. Thus this is prevented by default. BD718x7 has a quirk which may leave power output disabled after reset if enable/disable state was controlled by SW. Thus the SW control is only allowed for BD71837 bucks 3 and 4 by default. The impact of this limitation must be evaluated board-by board and restrictions may need to be modified. (Linux driver get's these limitations from DT and we may want to implement same on u-Boot driver).

We set MULT to 20, NUM to 4 and DENOM to 2, to get final 22 multiplier. But according to the RM, the NUM should always be less than the DENOM. So our setting violates the rule. Actually the ROM has already set the MULT to 22 and leave NUM/DENOM in default value. The calculated APLL PFD0 clock is 318.9888Mhz, which also meet the DDR requirement. To fix the issue, we remove the PLL settings in DCD to use default value from ROM, and only set the PFD0 FRAC.

For i.MX based devices it is crucial to have available the serial console before relocation (otherwise the board may hand). The device definition may be provided either via device tree description or with U_BOOT_DEVICE(mxc_serial) definition. In the latter case the device will not bind in U-Boot proper when DM_FLAG_PRE_RELOC is not set. The !CONFIG_IS_ENABLED(OF_CONTROL) #if check was set as a "workaround" for DM problem described in following commit 4687919684e0 ("serial: Remove DM_FLAG_PRE_RELOC flag in various drivers"). Let's look on this check more thoroughly - we add this flag if the board doesn't support OF_CONTROL. This is a bit strange as the serial_mxc.c can be used with CONFIG_DM_SERIAL but without corresponding device tree description (OF_CONTROL). In such case the aforementioned U_BOOT_DEVICE(mxc_serial) definition is used. Other boards/SoCs have this flag set unconditionally for serial driver.

After following commit 1d255904c306 ("ARM: dts: imx: imx53: Synchronize iMX53 DT with Linux") from the uart2 compatible the 'fsl,imx7d-uart' has been removed (which was correct). However, the root cause of the problem was the commit 98d62e618bb9 ("arm: imx: add i.MX53 Beckhoff CX9020 Embedded PC") which introduced this compatible. Moreover, without this patch all i.MX53 UARTs are not usable as neither 'fsl,imx53-uart' nor 'fsl,imx21-uart' are in compatible IDs in drivers/serial/serial_mxc.c file. The fix is to add 'fsl,imx53-uart' and 'fsl,imx21-uart' as compatibles for the aforementioned serial driver (those are also defined in the Linux kernel).

On the other hand on imx6 duallite/sole SATA is not available. Therefore sata_remove() is skipped according to a blacklist scheme. Adding further imx derivates is probably not recessary as they are usually not pin-compatible and therefore a different board with its own configuration.
