2019-07-24clk: initialize clk->data when using default xlateSekhar Nori
Right now when using clk_of_xlate_default(), clk->data remains un-initialized because clk_get_bulk() does not initialize memory on allocation of clock structure. This can cause problems when data is used to match if two clocks pointers are exactly the same underlying clocks, for example. Fix it by initializing clk->data to 0.

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>

2019-07-19dm: clk: Extend clk_get_parent_rate() to support CLK_GET_RATE_NOCACHE flagLukasz Majewski
If the CLK_GET_RATE_NOCACHE flag is set - the clk_get_parent_rate() provides recalculated clock value without considering the cache setting. 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.

2019-07-19dm: clk: Define clk_get_by_id() for clk operationsLukasz Majewski
This commit adds the clk_get_by_id() function, which is responsible for getting the udevice with matching clk->id. Such approach allows re-usage of inherit DM list relationship for the same class (UCLASS_CLK). As a result - we don't need any other external list - it is just enough to look for UCLASS_CLK related udevices.

2019-07-19dm: clk: Define clk_get_parent_rate() for clk operationsLukasz Majewski
This commit adds the clk_get_parent_rate() function, which is responsible for getting the rate of parent clock. Unfortunately, u-boot's DM support for getting parent is different (the parent relationship is in udevice) than the one in Common Clock Framework [CCF] in Linux. To alleviate this problem - the clk_get_parent_rate() function has been introduced to clk-uclass.c. Signed-off-by: Lukasz Majewski <lukma@denx.de> Reviewed-by: Peng Fan <peng.fan@nxp.com>

U-Boot's DM support for getting parent is different (the parent relationship is in udevice) than the one in Common Clock Framework [CCF] in Linux. To obtain the pointer to struct clk of parent the pdev->uclass_priv field is read via dev_get_clk_ptr() wrapper.

2019-07-19clk: Provide struct clk for fixed rate clock (clk_fixed_rate.c)Lukasz Majewski
Up till now the fixed rate clock ('osc') has been added to UCLASS_CLK without declaring struct clk. As a result it was only accessible by iterating the udevice's uclass list. 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.
