Now SVC driver has an access to APBs operational functions (coldboot, standby_boot, fw_flashing and poweroff), SVC driver can control APB's as per below rules, - If SVC goes down (poweroff state), it will also power off APBs and vice a versa for all operational states. - On boot, SVC will probe/populate APB device, but will not coldboot it. APBs will coldboot only after handshaking with SVC over wake/detect line. Note that, both APBs share same wake/detect line. So from user/developer perspective, it is highly recommended that they should use arche-platform interfaces, instead of individual apb interface, # echo [off/active/standby/fw_flashing] > /sys/devices/arche_platform.*/state Note: 'standby' mode is not supported as of now. Testing Done: Testd on EVT1.2 and DB3.5 platform. Signed-off-by: Vaibhav Hiremath <vaibhav.hiremath@linaro.org> Signed-off-by: Greg Kroah-Hartman <gregkh@google.com> |
