[PATCH 0/3] clk: meson: three small clk-pll fixes

From: Martin Blumenstingl

Hi Jerome,

while working on some changes for the 32-bit SoCs I hit a corner-case
in the HDMI PLL: there's some rate doubling going. The PLL only locks
in a specific rate range but the M/N table is not aware of that. This
means for now (I am planning to fix that) that we can end up in a
ituation where the PLL doesn't lock and meson_clk_pll_set_rate() is
supposed to still behave in this case. So here's three small patches
for that.

For me it's fine to queue these patches for -next. I am not aware of
any breakage upstream, only some of my pending patches prefer to have
these fixes.

Slightly unrelated: if you know anything about that clock doubling then
please let me know!


Best regards,
Martin


Martin Blumenstingl (3):
clk: meson: clk-pll: fix initializing the old rate (fallback) for a
PLL
clk: meson: clk-pll: make "ret" a signed integer
clk: meson: clk-pll: propagate the error from meson_clk_pll_set_rate()
