2019-07-19regulator: bd718x7: support ROHM BD71837 and BD71847 PMICsMatti Vaittinen
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).

The code responsible for setting proper values in the MUX registers (in the mxs_pinctrl_set_state()) has been ported from Linux kernel - SHA1: 17bb763e7eaf tag v5.1.11 from linux-stable. As the pinctrl node in the imx28.dtsi file has gpio pins nodes as subnodes, it was necessary to use 'dm_scan_fdt_dev()' (as a .bind method) to also make them 'visible' by the DM's "gpio_mxs" driver.

2019-07-19i.MX6: nand: add nandbcb command for imxShyam Saini
Writing/updating boot image in nand device is not straight forward in i.MX6 platform and it requires boot control block(BCB) to be configured. 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.

2019-07-19clk: sandbox: Add sandbox test code for Common Clock Framework [CCF]Lukasz Majewski
This patch provides code to implement the CCF clock tree in sandbox. It uses all the introduced primitives; some generic ones are reused, some sandbox specific were developed. In that way (after introducing the real CCF tree in sandbox) the recently added to clk-uclass.c: clk_get_by_id() and clk_get_parent_rate() are tested in their natural work environment. Usage (sandbox_defconfig and sandbox_flattree_defconfig): ./u-boot --fdt arch/sandbox/dts/test.dtb --command "ut dm clk_ccf" Signed-off-by: Lukasz Majewski <lukma@denx.de>
2019-07-19clk: sandbox: Adjust clk-mux.c to emulate reading divider value from HWLukasz Majewski
The generic mux clock code for CCF requires reading the clock multiplexer value from HW registers. As sandbox by design has readl() as no-op it was necessary to provide this value in the other way. The new field in the mux structure (accessible only when sandbox is run) has been introduced for this purpose. Signed-off-by: Lukasz Majewski <lukma@denx.de>

This may be necessary for some clocks tightly coupled with power domains (i.e. imx8), and prevents from reading invalid cached values.

2019-07-19clk: Port Linux common clock framework [CCF] for imx6q to U-boot (tag: v5.1.12)Lukasz Majewski
This patch brings the files from Linux kernel (linux-stable/linux-5.1.y SHA1: 5752b50477da)to provide clocks support as it is used on the Linux kernel with Common Clock Framework [CCF] setup. The directory structure has been preserved. The ported code only supports reading information from PLL, MUX, Divider, etc and enabling/disabling the clocks USDHCx/ECSPIx depending on used bus. Moreover, it is agnostic to the alias numbering as the information about the clock is read from the device tree. One needs to pay attention to the comments indicating necessary for U-Boot's driver model changes. If needed, the code can be extended to support the "set" part of the clock management.

Such approach allows re-usage of inherit DM list relationship for the same class (UCLASS_CLK).

This is a problem for clock code, which operates on pointers to struct clk (like clk_get_rate()), not udevices. After this change struct clk is accessible from udevice and udevice from struct clk.

2019-07-18blk: Invalidate block cache when switching hwpartWeijie Gao
Some storage devices have multiple hw partitions and both address from zero, for example eMMC. However currently block cache invalidation only applies to block write/erase. This can cause a problem that data of current hw partition is cached before switching to another hw partition. And the following read operation of the latter hw partition will get wrong data when reading from the addresses that have been cached previously. To solve this problem, invalidate block cache after a successful select_hwpart operation. Signed-off-by: Weijie Gao <weijie.gao@mediatek.com>
