From f79d35a25eb47b681d6c3c6f4c8aaba9175ec633 Mon Sep 17 00:00:00 2001 From: Dave Chapman Date: Tue, 2 May 2006 08:08:10 +0000 Subject: ipods - First implementation of pcf50605_init() function. This enables the power-out in the Dock connector, which may help getting some accessories working - if they don't need to talk to the ipod via the Apple Accessory Protocol. Thanks to julius in IRC for testing. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@9860 a1c6a512-1295-4272-9138-f99709370657 --- firmware/drivers/pcf50605.c | 13 +++++++++++++ firmware/drivers/power.c | 2 +- 2 files changed, 14 insertions(+), 1 deletion(-) (limited to 'firmware/drivers') diff --git a/firmware/drivers/pcf50605.c b/firmware/drivers/pcf50605.c index a8c61b1..0f71229 100644 --- a/firmware/drivers/pcf50605.c +++ b/firmware/drivers/pcf50605.c @@ -65,6 +65,12 @@ #define PSSC 0x18 #define PWROKM 0x19 #define PWROKS 0x1a +#define D1REGC1 0x24 + #define VOUT_3000mV 0xf5 + #define VOUT_3300mV 0xf8 +#define D2REGC1 0x25 +#define D3REGC1 0x26 + int pcf50605_read(int address) { @@ -101,3 +107,10 @@ void pcf50605_standby_mode(void) pcf50605_write(OOCC1, GOSTDBY | CHGWAK | EXTONWAK); } +void pcf50605_init(void) +{ + /* The following values were taken from the ipodlinux kernel source */ + pcf50605_write(D1REGC1, VOUT_3000mV); /* Unknown */ + pcf50605_write(D2REGC1, VOUT_3300mV); /* Dock Connector pin 17 */ + pcf50605_write(D3REGC1, VOUT_3000mV); /* Unknown */ +} diff --git a/firmware/drivers/power.c b/firmware/drivers/power.c index 9cc751e..c4b9fb5 100644 --- a/firmware/drivers/power.c +++ b/firmware/drivers/power.c @@ -85,7 +85,7 @@ void power_init(void) #endif #endif #elif CONFIG_CPU == PP5020 || CONFIG_CPU == PP5002 - /* TODO: Implement power_init() */ + pcf50605_init(); #else #ifdef HAVE_POWEROFF_ON_PB5 PBCR2 &= ~0x0c00; /* GPIO for PB5 */ -- cgit v1.1
