Changes since v7 (https://lkml.org/lkml/2016/10/31/296) * Add the APCS clock controller to the APCS driver to expose both the mailbox and clock controller functionality as discussed earlier: https://lkml.org/lkml/2016/11/14/860 * Changed the a53pll compatible string as suggested by Rob. Changes since v6 (https://lkml.org/lkml/2016/9/7/347) * Addressed various comments from Stephen Boyd Changes since v5 (https://lkml.org/lkml/2016/2/1/407) * Rebase to clk-next and update according to the recent API changes. Changes since v4 (https://lkml.org/lkml/2015/12/14/367) * Convert to builtin drivers as now __clk_lookup() is used Changes since v3 (https://lkml.org/lkml/2015/8/12/585) * Split driver into two parts - and separate A53 PLL and A53 clock controller drivers. * Drop the safe switch hook patch. Add a clock notifier in the clock provider to handle switching via safe mux and divider configuration. Changes since v2 (https://lkml.org/lkml/2015/7/24/526) * Drop gpll0_vote patch. * Switch to the new clk_hw_* APIs. * Rebase to the current clk-next. Changes since v1 (https://lkml.org/lkml/2015/6/12/193) * Drop SR2 PLL patch, as it is already applied. * Add gpll0_vote rate propagation patch. * Update/rebase patches to the current clk-next.
