From mboxrd@z Thu Jan 1 00:00:00 1970 From: Guru Das Srinagesh Subject: [PATCH v7 00/13] Convert period and duty cycle to u64 Date: Mon, 9 Mar 2020 12:35:03 -0700 Message-ID: Mime-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Return-path: Sender: linux-kernel-owner@vger.kernel.org To: linux-pwm@vger.kernel.org Cc: Thierry Reding , =?UTF-8?q?Uwe=20Kleine-K=C3=B6nig?= , Subbaraman Narayanamurthy , linux-kernel@vger.kernel.org, Guru Das Srinagesh List-Id: linux-pwm@vger.kernel.org Changes from v6: - Split out the driver changes out into separate patches, one patch per file for ease of reviewing. Changes from v5: - Dropped the conversion of struct pwm_capture to u64 for reasons mentioned in https://www.spinics.net/lists/linux-pwm/msg11541.html Changes from v4: - Split the patch into two: one for changes to the drivers, and the actual switch to u64 for ease of reverting should the need arise. - Re-examined the patch and made the following corrections: * intel_panel.c: DIV64_U64_ROUND_UP -> DIV_ROUND_UP_ULL (as only the numerator would be 64-bit in this case). * pwm-sti.c: do_div -> div_u64 (do_div is optimized only for x86 architectures, and div_u64's comment block suggests to use this as much as possible). Changes from v3: - Rebased to current tip of for-next. Changes from v2: - Fixed %u -> %llu in a dev_dbg in pwm-stm32-lp.c, thanks to kbuild test robot - Added a couple of fixes to pwm-imx-tpm.c and pwm-sifive.c Changes from v1: - Fixed compilation errors seen when compiling for different archs. Reworked the change pushed upstream earlier [1] so as to not add an extension to an obsolete API. With this change, pwm_ops->apply() can be used to set pwm_state parameters as usual.
