Subject: [PATCH v5 02/14] media: ov772x: correct setting of banding filter
Date: Sun, 6 May 2018 23:19:17 +0900 [thread overview]
Message-ID: <1525616369-8843-3-git-send-email-akinobu.mita@gmail.com> (raw)
In-Reply-To: <1525616369-8843-1-git-send-email-akinobu.mita@gmail.com>
The banding filter ON/OFF is controlled via bit 5 of COM8 register. It
is attempted to be enabled in ov772x_set_params() by the following line.
ret = ov772x_mask_set(client, COM8, BNDF_ON_OFF, 1);
But this unexpectedly results disabling the banding filter, because the
mask and set bits are exclusive.
On the other hand, ov772x_s_ctrl() correctly sets the bit by:
ret = ov772x_mask_set(client, COM8, BNDF_ON_OFF, BNDF_ON_OFF);
