[meta-ti] U-boot with TPS659037

This is based of the beagleboard_X15 board.c

The write to the PMIC to hold power on is limited to a 8 bit address and
the new PMIC has a longer address.

int board_late_init(void)

{

init_sata(0);

/*

 * DEV_CTRL.DEV_ON = 1 please - else palmas switches off in 8 seconds

 * This is the POWERHOLD-in-Low behavior.

 */

palmas_i2c_write_u8(TPS65903X_CHIP_P1, 0xA0, 0x1);

return 0;

}

We have attempted to use i2c_write and it still seems to not write.

Our current workaround is to have a uenvcmd =i2c mw 0x58 0x1A0 0x1 1  in
the uEnv.txt to do the i2cwite.

Any suggestions are appreciated

Thanks
