ARM: davinci: remove legacy clocks

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: 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: psc: introduce reset API

2013-01-22T12:12:59+00:00

Introduce an IP reset API for use on DaVinci SoC. There is no existing "reset" framework support for SoC devices. The remoteproc driver needs explicit control of the DSP's reset line. To support this, a new DaVinci specific API is added. This private API will disappear with DT migration. Some discussion regarding a proposed DT "reset" binding is here: https://patchwork.kernel.org/patch/1635051/ Modify davinci_clk_init() to set clk "reset" function for clocks that indicate PSC_LRST support. Also fix indentation issue with function opening curly brace. Signed-off-by: Robert Tivy [nsekhar@ti.com: rename davinci_psc_config_reset() to davinci_psc_reset()] Signed-off-by: Sekhar Nori

ARM: davinci: psc.c: change pr_warning() to pr_warn()

Change all pr_warning() calls to pr_warn(), as advised by checkpatch.pl. Signed-off-by: Robert Tivy Signed-off-by: Sekhar Nori

ARM: davinci: psc: fix incorrect offsets

2011-12-05T11:17:15+00:00

Seperate PDSTAT and PDCTL registers are defined for domain 0 and domain 1 where as the code always reads the domain 0 PDSTAT register and domain 1 PDCTL register. Fix this issue. While at it, introduce usage of macros for register masks to improve readability. Reviewed-by: Sergei Shtylyov Signed-off-by: Murali Karicheri Signed-off-by: Sekhar Nori

ARM: davinci: psc: fix incorrect mask

2011-12-05T11:17:14+00:00

There are 5 LSB bits defined in PDSTAT and the code currently uses a mask of 1 bit to check the status. Use a proper mask per the hardware specification. While at it, use a #define for the mask to improve readability. Reviewed-by: Sergei Shtylyov Signed-off-by: Murali Karicheri Signed-off-by: Sekhar Nori

davinci: enable forced transitions on PSC

2011-07-08T05:40:09+00:00

Some DaVinci modules like the SATA on DA850 need forced module state transitions. Define a "force" flag which can be passed to the PSC config function to enable it to make forced transitions. Forced transitions shouldn't normally be attempted, unless the TRM explicitly specifies its usage. ChangeLog: v2: Modified to take care of the fact that davinci_psc_config() now takes the flags directly. Signed-off-by: Sekhar Nori

davinci: pass clock flags to davinci_psc_config()

2011-07-08T05:21:40+00:00

Enabling or disabling a PSC can take certain modifiers like "disable with reset", "force enable/disable" and "enable/disable with local reset" apart from the regular clock gating functionality. Pass a flags argument to davinci_psc_config() so these variations can be supported there. At this time only "disable with reset" is supported, but other functionality will be added in subsequent patches. Signed-off-by: Sekhar Nori
