From 9bb13a6dc3a6f68c990264838ff0493d900c48d7 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Mon, 9 Jan 2006 15:25:37 -0200 Subject: V4L/DVB (3233): Fixed API to set I2S speed control - Created a new ioctl to control I2S speed. Old calls to an inadequate V4L2 API replaced.

Prevents that a radio tuner is initialized with a tv frequency or vice versa. - When switching to radio mode initialize the tuner with the last used radio frequency (this was already done for the TV mode). As a result of these changes the tuner module now remembers the last set radio and TV frequencies, which is what you would expect to happen. - Move out of range frequencies to the closest valid frequency as per v4l2 API spec. - Fix incorrect initial radio frequency (multiplier is 16000, not 16) - Add boundary check for out of range frequencies. - Use new flag to check if the order of the CB and freq. depends on the last set frequency. That is needed for some tuners or you can get static as a result. The flag is added for those tuners where I know that the datasheet indicates that this is necessary. - For this new check use the last set div value, not the last frequency as radio frequencies are always much higher due to the 16000 multiplier.
