Subject: [PATCH 0/2] media: rcar-vin: Mask access to VNCSI_IFMD register
Date: Thu, 12 Nov 2020 17:08:49 +0100	[thread overview]
Message-ID: <20201112160851.99750-1-jacopo+renesas@jmondi.org> (raw)

As reported in patch 2/2 commit message the the VNCSI_IFMD register
has the following limitations according to chip manual revision 2.20

- V3M, V3H and E3 do not support the DES1 field has they do not feature
a CSI20 receiver.
- D3 only supports parallel input, and the whole register shall always
be written as 0.

This patch upports the BSP change commit f54697394457
("media: rcar-vin: Fix VnCSI_IFMD register access for r8a77990") from
Koji Matsuoka

Tested on r-car E3 Ebisu.

Thanks
