bcm53xx: add clk tree driver
These patches are written by Broadcom and will be in mainline Linux kernel soon. I had some problems to get them backported to kernel 4.1, so currently they are only available for 4.3. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> SVN-Revision: 47253

+Subject: [PATCH] clk: iproc: Fix PLL output frequency calculation
+
+This patch affects the clocks that use fractional ndivider in their
+PLL output frequency calculation. Instead of 2^20 divide factor, the
+clock's ndiv integer shift was used. Fixed the bug by replacing ndiv
+integer shift with 2^20 factor.

+Subject: [PATCH 45/50] clk: iproc: Add PWRCTRL support
+
+Some iProc SoC clocks use a different way to control clock power, via
+the PWRDWN bit in the PLL control register. Since the PLL control
+register is used to access the PWRDWN bit, there is no need for the
+pwr_base when this is being used. A new flag, IPROC_CLK_EMBED_PWRCTRL,
+has been added to identify this usage. We can use the AON interface to
+write the values to enable/disable PWRDOWN.

+All writes to the PLL base address must be flushed if the

+necessary write and reads, we can make sure that any future code which

+Subject: [PATCH 48/50] clk: iproc: Split off dig_filter
+
+The PLL loop filter/gain can be located in a separate register on some
+SoCs. Split these off into a separate variable, so that an offset can
+be added if necessary. Also, make the necessary modifications to the
+Cygnus and NSP drivers for this change.

+Subject: [PATCH 49/50] clk: iproc: Separate status and control variables
+
+Some PLLs have separate registers for Status and Control. The means the
+pll_base needs to be split into 2 new variables, so that those PLLs can
+specify device tree registers for those independently. Also, add a new
+driver flag to identify this presence of the split, and let the driver
+know that additional registers need to be used.
