ARM: davinci: remove legacy clocks

2018-06-26T10:45:55+00:00

This removes the unused legacy clock code from arch/arm/mach-davinci/. Signed-off-by: David Lechner Reviewed-by: Sekhar Nori Signed-off-by: Sekhar Nori

ARM: davinci: normalize clk API

2017-07-27T11:15:29+00:00

davinci still has its own clk implementation, but lacks a clk_get_parent() helper, which can lead to link errors in randconfig builds. This adds the usual implementation. Acked-by: Sekhar Nori Signed-off-by: Arnd Bergmann

ARM: davinci: Make __clk_{enable,disable} functions public

2017-01-02T10:40:42+00:00

In some cases, there is a need to enable a clock as part of clock enable callback of a different clock. For example, USB 2.0 PHY clock enable requires USB 2.0 clock to be enabled. In this case, it is safe to instead call __clk_enable() since the clock framework lock is already taken. Calling clk_enable() causes recursive locking error. A similar case arises in the clock disable path. To enable such usage, make __clk_{enable,disable} functions publicly available outside of clock.c. Also, call them davinci_clk_{enable|disable} now to be consistent with how other davinci-specific clock functions are named. Note that these functions are not exported to drivers. They are meant for usage in platform specific clock management code. Signed-off-by: Alexandre Bailon Suggested-by: David Lechner Signed-off-by: Sekhar Nori

ARM: davinci: Move clock init after ioremap.

2016-04-27T10:33:49+00:00

Some clocks (such as the USB PHY clocks in DA8xx) will need to use iomem. The davinci_common_init() function must be called before the ioremap, so the clock init is now split out as separate function. Signed-off-by: David Lechner Signed-off-by: Sekhar Nori

ARM: davinci: clk: add set_parent callback for mux clocks

2016-04-14T10:01:48+00:00

Introduce a set_parent callback that will be used for mux clocks, such as the USB PHY muxes and the async3 clock domain mux. Signed-off-by: David Lechner [nsekhar@ti.com: checkpatch fixes] Signed-off-by: Sekhar Nori

ARM: davinci: make headers more local

2015-12-01T20:52:51+00:00

Some header files are never included outside of a mach-davinci directory and do not need to be made visible in include/mach, so let's just move them all down one level. Signed-off-by: Arnd Bergmann Acked-by: Sekhar Nori

ARM: davinci: clock: Correct return values for API functions

2015-10-07T11:11:29+00:00

Fix the values returned by the publicly used functions. These function should return 0 when they are called with clk == NULL in similar manner as the clock API does to avoid different behavior in drivers used by daVinci and other architectures.

ARM: davinci: Use standard logging styles

2014-11-18T15:36:41+00:00

Convert printks to pr_ and pr_warning to pr_warn. Other miscellanea: o Coalesce formats o Realign arguments o Use %s, __func__ instead of embedded function names o Add pr_fmt to mityomapl138 and mux Signed-off-by: Joe Perches Signed-off-by: Sekhar Nori

ARM: davinci: clock: return 0 upon error from clk_round_rate()

2013-11-27T09:18:33+00:00

clk_round_rate() should return 0 now upon an error, rather than returning a negative error code. This is because clk_round_rate() is being changed to return an unsigned return type rather than a signed type, since some clock sources can generate rates higher than (2^31)-1 Hz.

ARM: davinci: clk framework support for enable/disable functionality

2013-04-01T11:24:47+00:00

DaVinci clock implementation does not support clock enable/disable functionality on non-PSC clock nodes. On DA850 SoC, EHRPWM module requires support for enable/disable of TBCLK controlled using a system module register. This patch adds a method for enabling/disabling non-PSC clocks into DaVinci clock implementation. Signed-off-by: Philip Avinash Signed-off-by: Sekhar Nori
