From: Mauro Carvalho Chehab Date: Tue, 12 Jul 2005 20:58:55 +0000 (-0700) Subject: [PATCH] v4l: I2C Tuner X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f7ce3cc67052de63a29bad90110640b687d12058;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git [PATCH] v4l: I2C Tuner - Fixed a trouble on tuner-core that generates erros on computers with more than one TV card. - Rename tuner structures fields. - Tail spaces removed. - I2C cleanups and converged to a basic reference structure. - Removed unused structures. - Fix setting frequency on tda8290. - Added code for TEA5767 autodetection. - Standby mode support implemented. It is used to disable a non used tuner. Currenlty implemented on tea5767. - New macro: set_type disables other tuner when changing mode. - Some cleanups. - Use 50 kHz step when tunning radio for most tuners to improve precision.
