Subject: [PATCH] clk: ipq: support for resetting multiple bits
|
|
|
|
Current reset structure takes only one reset bit and
|
|
calculates the bitmask in its reset operation. Some of the
|
|
reset registers contains multiple bits in which each bit
|
|
will be associated with subsystem reset inside the block. To
|
|
reset properly the complete block, all the subsystem reset
|
|
should be triggered at same time i.e the register write
|
|
should go in one AHB write.
|
|
|
|
This patch adds the support for giving the complete bitmask
|
|
in reset structure and reset operation will use this bitmask
|
|
for all reset operations.
