This patch fixes thermal interrupts that did not happen when temprature changed.
Add the function rcar_gen3_thermal_update_threshold(), this function is used to
calculate the value written to the threshold registers REG_GEN3_IRQTEMP1 and
REG_GEN3_IRQTEMP2.
Is it really a error if the IRQ don't happen and the thermal framework
use the .set_trip() callback to move the window due to the polling
instead of a IRQ due to a rapid thermal increase? I think not. I do not
like this patch but I'm not expert on thermal subsystem so I'm open to
be proven wrong :-)
I'm investigating more about this issue!
This patch is based on renesas-bsp/rcar-3.5.4.rc2 !

This won't work I'm afraid as it can overflow. As the thcodes and ptat
values can be read from hardware there theoretical max size is 0xfff
according to the documentation. Those values are then used to calculate
a1, b1, a2 and b2 constants. If you can prove that no overflow can
happen I'm happy for this change as it increases accuracy. If so this
should be posted as a separate patch.
With this patch, when rcar_gen3_thermal_mcelsius_to_temp () is called,
since the mcelsius value was passed is calculated from the previous formula:
rcar_gen3_thermal_get_temp():
int mcelsius, val1, val2;
u32 reg;
/* Read register and convert to mili Celsius */
reg = rcar_gen3_thermal_read(tsc, REG_GEN3_TEMP) & CTEMP_MASK;
val1 = FIXPT_DIV(FIXPT_INT(reg) - tsc->coef.b1, tsc->coef.a1);
val2 = FIXPT_DIV(FIXPT_INT(reg) - tsc->coef.b2, tsc->coef.a2);
mcelsius = FIXPT_TO_MCELSIUS((val1 + val2) / 2);
/* Make sure we are inside specifications */
if ((mcelsius < MCELSIUS(-40)) || (mcelsius > MCELSIUS(125)))
return -EIO;
From int mcelsius values, val1, val2;
The reverse calculation I do not think will happen the overflow!
With the current situation, I am not clear about the high, low values
But with (a1, b1), (a2, b2)
tsc1->coef.a1 965 tsc1->coef.a2 953 tsc1->coef.b1 323853 tsc1->coef.b2

tsc3->coef.a1 947 tsc3->coef.a2 932 tsc3->coef.b1 325163 tsc3->coef.b2
325680
with all tscX, aX <=1000.
If the temperature is 1000celsius = 100 mcelsius.
val1 <100 * 1000 + 323853 = 1 000 323 853 <2 147 483 647 (max int value)
(In fact the temperature of the board could not get to 1000 celsius
degrees )
Here the current constant values are used.
But at future THCODE and PLAT values are read from registers
to calculate aX, bX, I do not know whether there really will be overflow
or not.
If you use this patches without this part.
I have received incorrect interrupts with H3ES1.1.
So I need to integrate this part to ensure correctly in testing.

My understanding of the thermal framework is that implementing
.set_trips() is correct and removing it here and rewriting is just
wrong. The driver should use the framework not do it's own thing, that
way all the DT properties set for hysteresis and such are used in a
correct way.

[PATCH] thermal: rcar_gen3_thermal: Fix does not have interrupts counting
From: Hoan Nguyen An
This patch fixes thermal interrupts that did not happen when temprature changed.
Add the function rcar_gen3_thermal_update_threshold(), this function is used to
calculate the value written to the threshold registers REG_GEN3_IRQTEMP1 and
REG_GEN3_IRQTEMP2.
This patch is based on renesas-bsp/rcar-3.5.4.rc2 !
