Hi Mike,

Please pull in these 3 patches that cleans up the SOCFPGA clock driver.

Hi Dinh,

Patch #2, "clk: socfpga: Look for the GPIO_DB_CLK by its offset" throws
the following error during compilation:

drivers/clk/socfpga/clk.c: In function ?socfpga_clk_recalc_rate?:
drivers/clk/socfpga/clk.c:238:27: error: invalid operands to binary & (have ?void *? and ?int?)
   if (socfpgaclk->div_reg & SOCFPGA_GPIO_DB_CLK_OFFSET)
                           ^

Compilation can continue with the following change:

I have not applied this change to the patch. Is there anything different
way of handling this that you would prefer?

Mike

Thanks,
