Subject: [PATCH V3 0/8] Add interconnect support to QSPI and QUP drivers
Date: Tue, 31 Mar 2020 16:39:28 +0530 [thread overview]
Message-ID: <1585652976-17481-1-git-send-email-akashast@codeaurora.org> (raw)
dt-binding patch for QUP drivers.
- https://patchwork.kernel.org/patch/11436621/ [Convert QUP bindings
to YAML and add ICC, pin swap doc]
dt-binding patch for QSPI.
- https://patchwork.kernel.org/patch/11436719/ [Convert QSPI binding
to YAML and add interconnect doc]
High level design:
- QUP wrapper/common driver.
Vote for QUP core on behalf of earlycon from probe.
Remove BW vote during earlycon exit call
- SERIAL driver.
Vote only for CPU/CORE path because driver is in FIFO mode only
Vote/unvote from qcom_geni_serial_pm func.
Bump up the CPU vote from set_termios call based on real time need
- I2C driver.
Vote for CORE/CPU/DDR path
Vote/unvote from runtime resume/suspend callback
As bus speed for I2C is fixed from probe itself no need for bump up.
- SPI QUP driver.
Vote only for CPU/CORE path because driver is in FIFO mode only
Vote/unvote from runtime resume/suspend callback
Bump up CPU vote based on real time need per transfer.
- QSPI driver.
Vote only for CPU path
Vote/unvote from runtime resume/suspend callback
Bump up CPU vote based on real time need per transfer.
Changes in V2:
- Add devm_of_icc_get() API interconnect core.
- Add ICC support to common driver to fix earlyconsole crash.
Changes in V3:
- Define common ICC APIs in geni-se driver and use it across geni based
I2C,SPI and UART driver.
