Now that we have clk_hw based provider APIs to register clks, we can get rid of struct clk pointers while registering clks in these drivers, allowing us to move closer to a clear split of consumer and provider clk APIs.

Make the clocks visible options that can be selected by anyone. This avoids the problems of: 1) Select is a reverse dependency and is hard for people to understand and can sometimes be a pain to track down 2) Build coverage goes down because configs are hidden 3) Code bloat Patch suggested by Stephen Boyd Signed-off-by:Jon Mason <jonmason@broadcom.com> Signed-off-by:

Add X-Gene PMD clock support. PMD clock is implemented for a single register field. Output rate = parent_rate * (denominator - scale) / denominator with - denominator = bitmask of register field + 1 - scale = values of register field For example, for bitmask is 0x7, denominator will be 8 and scale will be computed and programmed accordingly.

The addition of many gate clocks added two entries in an array for the same value: drivers/clk/meson/meson8b.c:479:10: error: initialized field overwritten [-Werror=override-init] [CLKID_GCLK_VENCI_INT] = &meson8b_gclk_venci_int.hw, [CLKID_GCLK_VENCI_INT] = &meson8b_gclk_vencp_int.hw, This was clearly an accident, and since all other identifiers are listed in the order in which they are defined, I'm changing the first one to CLKID_GCLK_VENCI_INT0, making it all consistent again.

This commit introduces the clocks found in the Allwinner A33 CCU. Since this SoC is very similar to the A23, and we share a significant share of the DTSI, the clock IDs that are going to be used will also be shared with the A23, hence the name of the various header files. Signed-off-by:

Some dividers might have a maximum value that is lower than the width of the register. Add a field to _ccu_div to handle those case properly. If the field is set to 0, the code will assume that the maximum value is the maximum one that can be used with the field register width. Otherwise, we'll use whatever value has been set.

This patch adds code instantiating the EPLL, which is used as the audio subsystem's root clock. The requirement to specify the external root clock in clocks property is documented. Having the consumer 'clocks' property ensures proper initialization order by explicitly specifying dependencies in DT. It prevents situations when the SoC's clock controller driver has initialized, the external oscillator clock is not yet registered and setting clock frequencies through assigned-clock-rates property doesn't work properly due to unknown external oscillator frequency.

Exynos5410 Audio Subsystem Clock Controller, comparing to the already supported IP block revisions, has additionally an I2S_MST divider so a new compatible string is added. It is not clear from the Exynos5410 User's Manual released on 2012.03.09 where in the clock tree the I2S_MST clock divider can be found exactly so this clock is left unimplemented for now.

This patch moves the samsung_cmu_info struct instances to initconst section, this decreases the kernel image size by 784 bytes, which makes zImage smaller by 480 bytes. The patch increases .init.rodata section size by 780 bytes but decreases .init.text section size by 1564 bytes. Size of the drivers/clk/samsung/clk-exynos5260.o object file is 29100 bytes without the patch and 28316 after applying the patch. The section size differences are as below: 15c15 < 3 .init.text 000006b8 00000000 00000000 00000034 2**2 --- > 3 .init.text 0000009c 00000000 00000000 00000034 2**2 25c25 < 8 .init.rodata 00003f6c 00000000 00000000 00002f20 2**2 --- > 8 .init.rodata 00004278 00000000 00000000 00002904 2**2 Signed-off-by:
