From: Oleh Kravchenko Date: Sat, 22 Apr 2017 15:47:13 +0000 (-0300) Subject: [media] cx231xx: Initial support Astrometa T2hybrid X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0f42b331b6f7e9281381cc240d8c3a27cf0fa5ca;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git [media] cx231xx: Initial support Astrometa T2hybrid This patch provide only digital support; The device is based on 24C02N EEPROM, Panasonic MN88473 demodulator, Rafael Micro R828D tuner and CX23102-11Z chipset; USB id: 15f4:0135. Status: - DVB-T/T2 works fine; - Composite works fine; - Analog not implemented.
