Subject: [PATCH v1 1/3] staging: media: imx: imx7-mipi-csis: Dump MIPI_CSIS_FRAME_COUNTER_CH0 register
Date: Thu,  6 Jan 2022 19:24:39 +0200	[thread overview]
Message-ID: <20220106172441.7399-2-laurent.pinchart@ideasonboard.com> (raw)
In-Reply-To: <20220106172441.7399-1-laurent.pinchart@ideasonboard.com>

The frame counter is useful debugging information, add it to the
register dump printed by mipi_csis_dump_regs().
