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)
                           ^

make[2]: *** Waiting for unfinished jobs....
make[1]: *** [drivers/clk] Error 2
make[1]: *** Waiting for unfinished jobs....
make: *** [drivers] Error 2

Compilation can continue with the following change:

diff --git a/drivers/clk/socfpga/clk.c b/drivers/clk/socfpga/clk.c
index 9350071..da6d82c 100644

 		else
 			div = (1 << val);

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

Mike
