* [PATCH V6 2/2] regulator: mt6323: Add support for MT6323 regulator 2016-02-17 11:37 ` John Crispin @ 2016-02-17 11:37 ` John Crispin -1 siblings, 0 replies; 21+ messages in thread From: John Crispin @ 2016-02-17 11:37 UTC (permalink / raw) To: Liam Girdwood, Mark Brown, Matthias Brugger Cc: linux-kernel, linux-arm-kernel, linux-mediatek, Chen Zhong, John Crispin From: Chen Zhong <chen.zhong@mediatek.com> The MT6323 is a regulator found on boards based on MediaTek MT7623 and probably other SoCs. It is a so called pmic and connects as a slave to SoC using SPI, wrapped inside the pmic-wrapper.

* [PATCH V6 2/2] regulator: mt6323: Add support for MT6323 regulator @ 2016-02-17 11:37 ` John Crispin 0 siblings, 0 replies; 21+ messages in thread From: John Crispin @ 2016-02-17 11:37 UTC (permalink / raw) To: linux-arm-kernel From: Chen Zhong <chen.zhong@mediatek.com> The MT6323 is a regulator found on boards based on MediaTek MT7623 and probably other SoCs. It is a so called pmic and connects as a slave to SoC using SPI, wrapped inside the pmic-wrapper.

You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail. Thanks, Mark >From 17871815a825e62bb49d2c6be1a4c9409eb2faac Mon Sep 17 00:00:00 2001 From: Chen Zhong <chen.zhong@mediatek.com> Date: Wed, 17 Feb 2016 12:37:36 +0100 Subject: [PATCH] regulator: mt6323: Add support for MT6323 regulator The MT6323 is a regulator found on boards based on MediaTek MT7623 and probably other SoCs. It is a so called pmic and connects as a slave to SoC using SPI, wrapped inside the pmic-wrapper.

You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail.

You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced.

You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced.

You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail.

You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced.
