x86: Add a clock driver for Intel devices

2020-02-07T14:41:24Z

So far we have avoided adding a clock driver for Intel devices. But the Designware I2C driver needs a different clock (133MHz) on Intel devices than on others (166MHz). Add a simple driver that provides this information. This driver can be expanded later as needed. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

dm: core: Create a new header file for 'compat' features

2020-02-06T02:33:46Z

At present dm/device.h includes the linux-compatible features. This requires including linux/compat.h which in turn includes a lot of headers. One of these is malloc.h which we thus end up including in every file in U-Boot. Apart from the inefficiency of this, it is problematic for sandbox which needs to use the system malloc() in some files. Move the compatibility features into a separate header file.

dm: core: Require users of devres to include the header

2020-02-06T02:33:46Z

At present devres.h is included in all files that include dm.h but few make use of it. Also this pulls in linux/compat which adds several more headers. Drop the automatic inclusion and require files to include devres themselves. This provides a good indication of which files use devres. Signed-off-by: Simon Glass Reviewed-by: Anatolij Gustschin

clk: Rename free() to rfree()

2020-02-06T02:33:46Z

This function name conflicts with our desire to #define free() to something else on sandbox. Since it deals with resources, rename it to rfree(). Signed-off-by: Simon Glass

arm: rockchip: Add common cru.h

2020-01-30T03:44:01Z

Few of the rockchip family SoC atleast rk3288, rk3399 are sharing some cru register bits so adding common code between these SoC families would require to include both cru include files that indeed resulting function declarations error. So, create a common cru include as cru.h then include the rk3399 arch cru include file and move the common cru register bit definitions into it. The rest of rockchip cru files will add it in future.

clk: imx: pllv3: fix potential 'divide by zero' in av_set_rate()

2020-01-26T20:57:08Z

Guard 'parent_rate==0' to prevent 'divide by zero' issue in clk_pplv3_av_set_rate(). If it is 0, let's return with -EINVAL. Signed-off-by: Giulio Benetti

clk: imx: pllv3: fix potential 'divide by zero' in av_get_rate()

Guard 'mfd==0' to prevent 'divide by zero' issue in clk_pplv3_av_get_rate(). If it is 0, let's return with EIO since mfd should never be 0 at all. Signed-off-by: Giulio Benetti
