ptp_qoriq: fix overflow in ptp_qoriq_adjfine() u64 calcalation

2021-03-24T19:10:03Z

Current calculation for diff of TMR_ADD register value may have 64-bit overflow in this code line, when long type scaled_ppm is large. adj *= scaled_ppm; This patch is to resolve it by using mul_u64_u64_div_u64(). Signed-off-by: Yangbo Lu Signed-off-by: David S. Miller

ptp: ptp_clockmatrix: clean-up - parenthesis around a == b are unnecessary

ptp: ptp_clockmatrix: Coding style - tighten vertical spacing.

2021-02-17T21:49:26Z

Code clean-up. * Remove blank line between variable declarations. * Remove blank line between: err = blah(...) if (err) ... * Remove unnecessary blank line before/after loop constructs. Signed-off-by: Vincent Cheng Signed-off-by: David S. Miller

ptp: ptp_clockmatrix: Clean-up dev_*() messages.

2021-02-17T21:49:26Z

Code clean-up. * Remove unnecessary \n termination from dev_*() messages. * Remove 'char *fmt' to define strings to stay within 80 column limit. Not needed since coding guidelines increased to 100 columns limit. Keeping format in place allows static code checkers to validate the arguments. * Tighten up vertical spacing.

ptp: ptp_clockmatrix: Add alignment of 1 PPS to idtcm_perout_enable.

2021-02-17T21:49:25Z

When enabling output using PTP_CLK_REQ_PEROUT, need to align the output clock to the internal 1 PPS clock. Signed-off-by: Vincent Cheng Acked-by: Richard Cochran Signed-off-by: David S. Miller

ptp: ptp_clockmatrix: Add wait_for_sys_apll_dpll_lock.

2021-02-17T21:49:25Z

Part of the device initialization aligns the rising edge of the output clock to the internal 1 PPS clock. If the system APLL and DPLL is not locked, then the alignment will fail and there will be a fixed offset between the internal 1 PPS clock and the output clock. After loading the device firmware, poll the system APLL and DPLL for locked state prior to initialization, timing out after 2 seconds.

ptp: ptp_ines: prevent build when HAS_IOMEM is not set

2021-01-07T00:17:23Z

ptp_ines.c uses devm_platform_ioremap_resource(), which is only built/available when CONFIG_HAS_IOMEM is enabled. CONFIG_HAS_IOMEM is not enabled for arch/s390/, so builds on S390 have a build error: s390-linux-ld: drivers/ptp/ptp_ines.o: in function `ines_ptp_ctrl_probe': ptp_ines.c:(.text+0x17e6): undefined reference to `devm_platform_ioremap_resource' Prevent builds of ptp_ines.c when HAS_IOMEM is not set.
