Date: Sat, 17 Oct 2020 00:56:02 +0800 Message-Id: <20201016165602.55720-2-zhouyanjie@wanyeetech.com> X-Mailer: git-send-email 2.11.0 In-Reply-To: <20201016165602.55720-1-zhouyanjie@wanyeetech.com> References: <20201016165602.55720-1-zhouyanjie@wanyeetech.com> MIME-Version: 1.0 Precedence: bulk List-ID: X-Mailing-List: devicetree@vger.kernel.org The new OST has one global timer and two or four percpu timers, so there will be three combinations in the upcoming new OST driver: the original GLOBAL_TIMER + PERCPU_TIMER, the new GLOBAL_TIMER + PERCPU_TIMER0/1 and GLOBAL_TIMER + PERCPU_TIMER0/1/2/3, For this, add the macro definition about OST_CLK_PERCPU_TIMER0/1/2/3. And in order to ensure that all the combinations work normally, the original ABI values of OST_CLK_PERCPU_TIMER and OST_CLK_GLOBAL_TIMER need to be exchanged to ensure that in any combinations, the clock can be registered (by calling clk_hw_register()) from index 0.
