Subject: [PATCH RFC v8 07/21] ARM: imx6q: clk: Change hsi_tx clock to be a shared clock gate
Date: Wed, 31 Dec 2014 16:23:25 +0800 [thread overview]
Message-ID: <1420014219-915-8-git-send-email-Ying.Liu@freescale.com> (raw)
In-Reply-To: <1420014219-915-1-git-send-email-Ying.Liu@freescale.com>
The CG8 field of the CCM CCGR3 register is named as 'mipi_core_cfg'
clock, according to the i.MX6q/sdl reference manuals. This clock is
actually the gate for several clocks, including the hsi_tx_sel clock's
output and the video_27m clock's output. So, this patch changes the
hsi_tx clock to be a shared clock gate.
