RSB is faster and more efficient, and it has a simpler driver. As long as the PMIC is returned to I2C mode after use, the rich OS can later use either bus. Change-Id: I0c5f32e88a090c8c5cccb81bd24596b301ab9da7 Signed-off-by:Samuel Holland <samuel@sholland.org>

This gives the rich OS the flexibility to choose between I2C and RSB communication. Since a runtime address can only be assigned once after entering RSB mode, it also lets the rich OS choose any runtime address. Signed-off-by: -

None of the other drivers (Linux, U-Boot, Crust) need to lower the bus clock frequency to switch the PMIC to RSB mode. That logic is not needed here, either. The hardware takes care of running this transaction at the correct bus frequency. Signed-off-by:

Current implementation doesn't support change of div1 value if clk has 2 divisor because div1 clk is the parent of the div2 clk and div2 clk does not have SET_RATE_PARENT flag. This causes div1 value to be fixed and only value of div2 will be adjusted according to required clock rate. Example: Consider a case of nand_ref clock which has 2 divisor and 1 mux. The frequency of mux clock is 1500MHz and default value of div1 and div2 is 15 and 1 respectively. So the final clock will be of 100MHz. When driver requests 80MHz for nand_ref clock, clock framework will adjust the div2 value to 1 (setting div2 value 2 results final clock to 50MHz which is more inaccurate compare to 100Mhz) which results final clock to 100MHz. Ideally the value of div1 and div2 should be updated to 19 and 1 respectively so that final clock goes to around 78MHz. This patch fixes above problem by allowing change in div1 value. Signed-off-by:

For the current XilPM calls, The handler of IPI returns information with 16 Bytes data. So during QueryData API call for the ClockName and PinFunctionName, response data(name of clock or function) response[0..3] are used to return name. And status is not being returned for such API. Updated XilPM calls reply in a consistent way and The handler of IPI return information with 32Bytes data. Where response[0] always set to status. For the version-2 of QueryData API, during call for the ClockName and PinFunctionName, response data(name of clock or function) get as response[1...4]. To support both the version of QueryData API, added version based compatibility by the use of feature check. Signed-off-by:

Existing code passes ACPU0 to LibPM as node_id in set_wakeup_source() call because last suspending core will be ACPU0 in most of the case. Now it may be possible that user may disable the ACPU0 using hot-plug and after that it suspends Linux. So in that case ACPU0 will not be last suspending core. To overcome above scenario, pass the current running processor ID while calling set_wakeup_source(). Signed-off-by:

FORCE target is used as a dependency for other file targets which needs to be always rebuilt. .PHONY target is standard Makefile target which specify non-file targets and therefore needs to be always rebuilt. Targets clean, realclean and distclean are .PHONY targets used to remove built files. Correctly set that mrvl_clean target is prerequisite for these clean targets to ensure that built files are removed. Finally this change with usage of FORCE target allows to remove mrvl_clean hack from the prerequisites of a8k ${DOIMAGETOOL} target which was used just to ensure that ${DOIMAGETOOL} is always rebuilt via make subprocess.
