  sh: clkfwk: modify for_each_frequency end condition
  sh: fix clk_get() error handling
  sh: clkfwk: Fix fault in frequency iterator.
  sh: clkfwk: Add a helper for rate rounding by divisor ranges.
  sh: clkfwk: Abstract rate rounding helper.
  sh: clkfwk: support clock remapping.
  sh: pci: Convert to upper/lower_32_bits() helpers.
  sh: mach-sdk7786: Add support for the FPGA SRAM.
  sh: Provide a generic SRAM pool for tiny memories.
  sh: pci: Support secondary FPGA-driven PCIe clocks on SDK7786.
  sh: pci: Support slot 4 routing on SDK7786.
  sh: Fix up PMB locking.
  sh: mach-sdk7786: Add support for fpga gpios.
  sh: use pr_fmt for clock framework, too.
  sh: remove name and id from struct clk
  sh: free-without-alloc fix for sh_mobile_lcdcfb
