| Subject: media: cx23885: Set subdev host data to clk_freq pointer |
| |
| From: Brad Love <brad@nextdimension.cc> |
| |
| [ Upstream commit 5ceade1d97fc6687e050c44c257382c192f56276 ] |
| |
| Currently clk_freq is ignored entirely, because the cx235840 driver |
| configures the xtal at the chip defaults. This is an issue if a |
| board is produced with a non-default frequency crystal. If clk_freq |
| is not zero the cx25840 will attempt to use the setting provided, |
| or fall back to defaults otherwise. |
