| | | | | | | | | | | | | | | | | | | | The ULONG_MAX value on 32 bit compilers is +4,294,967,295 and when divided with some high frequencies, it could lead to min_div > max_div.

* | clk: qcom: clock-generic: Fix handoff for mux_div clockTaniya Das2016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current implementation would check for the parent rate and decide the handoff state of the clock, which is not true for mux clocks. With this logic the function returns 'enabled' even when the clock downstream of this clock is disabled. The handoff code will unnecessarily enable the current parent of this clock. If this function always returns 'disabled' and a clock downstream is on, the clock handoff code will bump up the ref count for this clock and its current parent as necessary. The clocks without an actual HW gate can always return handoff disabled. Change-Id: I1f06842e2761b336b49a9390a556064de44f2e36 Signed-off-by: Taniya Das <tdas@codeaurora.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement dsi related clocks framework so that dsi vco pll related function be called to output correct vco rate base on byte clock rate. After that pixel clock rate can be achieved through MND setting.

* | clk: mdss: fix pll 1 leakage issue by calling power down sequenceHuaibin Yang2016-03-23
| | | | | | | | | | | | | | | | | | To completely shutdown pll 1, power down sequence has to be called. This is different from the old sequence where disable pll sequence acturally turn off pll.
