* msm: kgsl: Add a check for valid frequency of RBBM timer clockArchana Obannagari2018-02-15
| | | | | | | | | | rbbmtimer_clk hardwired fixed XO frequency 19.2Mhz. clock_round_rate() for RBBM timer clock fails with -EPERM as it is fixed.

| * msm: kgsl: Remove incorrect check to cap AB vote to IB voteDeepak Kumar2017-03-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For dual channel DDR, IB vote from client is half of actual IB vote as IB vote calculation on client side doesn't consider number of DDR channels. ICB driver takes care of multiplying the client IB vote with number of DDR channels. This change removes the AB capping check to avoid the scenarios where AB vote > actual IB vote/2 but gets capped to actual IB vote/2 because client side IB vote is half of actual IB vote. Removal of this check will not impact single channel DDR targets because of the way AB value is calculated. In case of honest BW voting, AB will always be less than IB as AB calculation doesn't consider RAM wait value. In case of unhonest vote, AB value is always caluclated as some percentage of IB vote and this percentage value is always <=100%.
