This is the driver for the Power Sleep Controller (PSC) hardware
found on DM SoCs as well Keystone SoCs (c6x). This driver borrowed
code from arch/arm/mach-davinci/psc.c and implemented the driver
as per common clock provider API. The PSC module is responsible for
enabling/disabling the Power Domain and Clock domain for different IPs
present in the SoC. The driver is configured through the clock data
passed to the driver through struct clk_psc_data.

Here is some pedantic stuff if you're really bored:

diff --git a/drivers/clk/davinci/clk-psc.c b/drivers/clk/davinci/clk-psc.c
(...)
+ ptcmd = 1 << domain;
ptcmd = BIT(domain);

+ pdctl = readl(psc_base + PDCTL + 4 * domain);
+ pdctl |= 0x100;
pdctl |= BIT(8); /* and here a comment explaing what on earth that means */

+ } else {
+ ptcmd = 1 << domain;
ptcmd = BIT(domain);

Yours,

Linus,

Thanks. I will fix the above and add your Acked-by in the next revision of the patch.
