Subject: [PATCH 5.4 17/34] net: stmmac: dwmac-meson8b: fix mask definition of the m250_sel mux
Date: Sat, 19 Dec 2020 14:03:14 +0100 [thread overview]
Message-ID: <20201219125342.231695087@linuxfoundation.org> (raw)
In-Reply-To: <20201219125341.384025953@linuxfoundation.org>
From: Martin Blumenstingl <martin.blumenstingl@googlemail.com>
[ Upstream commit 82ca4c922b8992013a238d65cf4e60cc33e12f36 ]
The m250_sel mux clock uses bit 4 in the PRG_ETH0 register. Fix this by
shifting the PRG_ETH0_CLK_M250_SEL_MASK accordingly as the "mask" in
struct clk_mux expects the mask relative to the "shift" field in the
same struct.
While here, get rid of the PRG_ETH0_CLK_M250_SEL_SHIFT macro and use
__ffs() to determine it from the existing PRG_ETH0_CLK_M250_SEL_MASK
macro.
