2023-02-22btpower: Set enable_irq_wake when BT turn onVic Huang
Set enable_irq_wake when BT turn on Set disable_irq_wake when BT turn off Bug: 267961645 Bug: 265610362 Test: 1. Basic functions test PASS 2. BCST PASS 3. Power automation test PASS 4. Manual power measurement PASS 5. SDS stability test PASS 6. Issue verified PASS Change-Id: I58839b7999dd46f6ac3a7047239a88ca850731de (cherry picked from commit 1ad11a6b83f97229ef34e527e21e3ef096df3875)
2022-07-21Bluetooth: Get idle IP right after GPIO initializedandroid-13.0.0_r0.93android-gs-felix-5.10-android13-d3Cheney Ni
We initialize the idle IP state with RFKILL probing, so have to get the idle IP before that. Bug: 238163307 Signed-off-by: Cheney Ni <cheneyni@google.com> Change-Id: Ie28d70b24d703715e0849ff90daaf9458c2c9b26

2022-07-07Bluetooth: Using logbuffer in btpower driver to enhance debuggingCheney Ni
Record useful driver messages in the logbuffer cache, and dump them via device node /dev/logbuffer_btpower once vendor HAL detecting errors. Bug: 229691092 Change-Id: Ifbcdaf4f5bfcec7826f7a35b79a0f34291b03bb8 Signed-off-by: Cheney Ni <cheneyni@google.com>
2022-04-20btpower: mechanism to handle OOBS flip and release carefullyCheney Ni
We remember previous HOST_WAKE gpio state, so can compare with the IRQ value if it changes quickly. The vendor HAL uses this information to fine-control OOBS state. This change also adds the release operation for unregistering OOBS control.

2022-04-19Add out of band sleep support to bluetooth driverBalakrishna Godavarthi
This change adds out of band sleep support to bluetooth power driver. This feature will be enabled when macro CONFIG_MSM_BT_OOBS is define.

2021-12-11btpower: acquire GPIO while probingCheney Ni
Allocate all necessary GPIO pins specified at the device tree while this driver probing, error out if any failure, and release them while removing the driver. There are two macro helpers for setting and getting GPIO values. Bug: 202113218 Test: manually Signed-off-by: Cheney Ni <cheneyni@google.com> Change-Id: Ie0fbe12352eb73d983cf1a6fe4bddd74d5b55b00
2021-12-08btpower: Embeds cdev within driver data structureCheney Ni
In order to access driver data inside file ioctl calls, this CL embeds the cdev within the driver data structure, and converts to the whole driver data while file opening. The global driver data is no longer used. Bug: 202113218 Test: manually Signed-off-by: Cheney Ni <cheneyni@google.com> Change-Id: I45ebda47d04d44ed1ea02262a14f7723b33b675b
