The i2c-mux-gpio driver is a handy driver to have in your bag of tricks, but it currently only works with DT-based firmware. Enable this driver on ACPI platforms as well. The first patch is a little dinky. Peter, if it turns out you'd rather just take this all as a single patch, feel free to squash the first patch into the second. Or I can resend a squashed patch if needed. Changes in v3: - Introduced minor &pdev->dev to dev refactor (Peter) - Update commit message again (Peter) - Added missing \n (Peter) - adr64 overflow check (Peter) - Don't initialize child (Peter) - Limit scope of dev_handle (Peter) Changes in v2: - Make it compile properly when !CONFIG_ACPI (Randy) - Update commit message regarding i2c-parent (Peter) Evan Green (2): i2c: i2c-mux-gpio: Factor out pdev->dev in _probe_dt() i2c: i2c-mux-gpio: Enable this driver in ACPI land drivers/i2c/muxes/i2c-mux-gpio.c | 112 ++++++++++++++++++++++--------- 1 file changed, 82 insertions(+), 30 deletions(-) -- 2.26.2
